[U-Boot-Users] SMC driver problem

[Robert Schwebel]

Hi, 

I've just tried to track down the SMSC driver problem which was recently
reported on this list. After the MMU allocates a block for a sent packet
in smc_send_packet() there is a FIXME comment in the sourcecode: 

- when I add puts("x"); after this comment it works. 
- when I remove it it hangs. 
- when I add the content of the putx() function (the register
  operations) to the same location it hangs. 
- when I add a function containing the register operation and call this
  function after the comment it hangs. 
- when I add a function which calls the function from the last step it
  works - this is the same constellation as with the puts() call. 

All this looks like some kind of a memory management or stack problem
for me; perhaps anybody else has an idea what might go on? 

Robert
